Wind Power Generators

In Wind Power Generator, deep groove ball bearings with inner ring insulation coating are used to prevent damage due to current passage.

Due to the voltage transformation, a high frequency current would flow through both bearings in the wind power generator.
The best possible protection against flow of current for these deep groove ball bearings is the 200-250μm coating on the inner ring.
For example, 6326/C3VL2071, 6328/C3Vl2071, 6332M/C3VL2071 and 6330M/C3VL2071.
